Virtual reality clips are only available for brands to post organically to their page, but based on Facebook's heavy push with autoplay videos, it's likely they'll eventually be packaged into ads.

As Facebook gains steam as a major force in video advertising, virtual reality could add a bit of a wow factor for brands. YouTube offers a similar product, but Facebook has been working to quash complaints from advertisers that want better buying options and better data about their campaigns. Just last week, the Menlo Park, Calif.-based company rolled out a premium buying option and viewability verification from Moat.

"Our goal at Facebook is to connect you with the people and things that matter, every single day," Facebook said in a blog post. "Over time, we've seen that people enjoy more immersive content in their News Feeds. This is one reason video has been so successful on Facebook, and we're excited to take it a step further with 360 video."
